To all whom it may concern:

Be it knownthat we, HERMAN PARrnR'r, EDWARD Bon-KnNKAMr, M and Louis S'r'ooK- srrnoar, citizens of the United States, residing at St. Louis,'State of hLl-issouri, have invented certain new 'and'use-rul Improvements in GasoleneBurners, of which the following is a specification, reference being had therein to the accompanying drawing.

Our invention relates to improvementsin gasolene burners, and pertains to that type of burner in'which thegasolene is vaporized or evaporated in the presence of air and passes downwardlythrough a tube to'the lower end of the burner. v

The object of our invention is to provide means whereby the burner may be quickly started in cold Weather with heavy gasolene and in order to accomplish this, we place an auxiliary torch or burner under the hot air flue forheating the air in starting the evaporization of the gasolene.

Another object of our invention is'to provide a burner of this characterin which a specially designed hood'an'd sub-burner -are used and having certain details of structure and operation, hereinafter more fully set forth.

It is well known to those skilled in the art that for'several yearspast the ga'solene furnished to the public has gradually become heavier and more dillicult'to thoroughly and rapidly evaporate in the'presence of air, and for this reason the heavy grade of gasolene furnished to the'p'ub'lic has'not been efliciently evaporated, taken care of and thoroughly mixed with the air in the construction ofevaporator'usedfin this type of'stoves with the lighter grades of gasolene which were fu'rnishedto the public at the time this class'of stove was first successfully placed upon the market.

Referring now to the drawings Figure l is an enlarged side elevation of a gasolene burner of the type to which our invention relates, the burner and the evapo rating tube being shown partly in vertical section.

Fig. 2 is a detached perspective view of the sub-burner and cap therefor.

Fig. 3 is a top plan view of Fig, 1, showing the air and gas evaporatortube broken away. U

Fig. at is a-perspectlve view oftheauxiliary torchfo-r starting the burner in operaon, Fig. 5 is a vertical sectional view, Fig. 6 is a transverse sectional viewjof the gasolene burner showing a modified form, or" feeding heated air to the vaporizer. Referring now to the drawings, L is" the burner or the type well-known in the art with theexception or a slight modification 01 the burner cap and sub-burner, which we will proceed to describe. This burner .consists ofthe cylindrical body port-ion 2, having a cylindrlcal, vertical central tubev 3 therein, said tube having its upper end reduced, as indicated at 3. Resting upon the upper end ofthe tube 3 is ahcap a, which has a central downwardly disposed cylindrical portiont, resting upon the upper reduced end ofthe tube 3. Supported by the upper end of the tube 3 and spaced from the cap at, is what is known as the burner cap, 5, of the form. clearly shown in Fig. 1 of the drawings. The lower end of the tube 3, is provided with a sub-burner 6, having the openings 7 therein, and a central opening through which extends a short tube 8, which also passes downwardly through a central hole in the bottom 9 of the body 2, and by means of which the central tube 3 is supplied with air to support combustion, as is clearly shownin F ig. 1 of the drawing. The vertical tube 3, adjacent its upper end, is provided with an outwardly extending circular flange 9, communicating with an opening 10 in the tube 3. Fitting within the flange 9 and communicating with an opening 10 is a short tube 11, which extends outward-1y through the body 2 and a slight distance beyond the same.

An air intake tube 12 is arranged ina horizontal position and has its ends terminating at one side adjacent the burner tube as shown in Fig. 3 or the drawing. The end of the tube 12 is open to allow air to pass thereto. The tube 12 is bent upwardly, as indicated at 13, and then outwardly, as indicated at 14, and communicates with an evaporating chamber 15. This chamber 15 isprovided with a vertically disposed elongated evaporating tube 16 arranged therein and spaced from the walls thereof, as'cl'early shown in Fig. 1 of the drawing. l V Y The upper end of the chamber 15"directly over the evaporating tube 16 is provided with an oil supply 16 which is adapted to discharge directly upon the upper end of the evaporating tube. The evaporator 15 has its lower end contracted, as indicated at 17, and into which fits the upper end 18 of the vapor tube 19. The perforated evaporator tube 16 fits within the upper end of the upwardly turned end 18 of the vapor tube and owing to the contracted end 17 of the evaporator chamber 15 it will be seen that the evaporator tube is spaced from the evaporator chamber throughout its entire length. The lower end of the vapor tube 19 communicates with the lower end of the burner tube 2, for supplying the burner with vapor, as is well understood by those skilled in the art.

The air tube 12, as clearly shown in Fig. 3, of the drawing, is atone side of the burner tube 2 and has connected theretoa downwardly curved tube 20, which surrounds the extension of'the tube 11 on the outside of the burner tube 2, and has its ends spaced a slight distance from the burner to allow a certain amount of fresh air to be drawn inwardly as the hot air passes from the tube 11.

Below the tube 12 is arranged an inverted V-shaped housing 21, which has its upper end open, as indicated at 22, and at its ends the upwardly and outwardly extending ears and 24, which are secured to the lower face of the tube 12, directly below the same. This housing 21 has its lower end open and has placed therein a plate 25, which has its ends a short distance from the side walls thereof. Supported by the plate 25 are the obliquely arranged perforated plates 26, extending parallel with the side walls of the housing and spaced therefrom, said plates terminating in a vertical line with the opening in the upper end of the housing. One end 27 of the housing is provided with an opening 28, through which the torch 29 passes and is adapted to burn within the housing between the perforated plates 26 and the plate 25. The torch, as shown, is of a cylindrical form having its outer end perforated, as indicated at 30, and its outer and its opposite end is provided with a handle 31 whereby the torch may be readily handled. The end of the torch adjacent the perforations 30 is filled with an absorbent asbestor which absorbs oil but allows it to freely burn through the opening as is readily understood. The torch may be dipped into a can of oil, but we prefer to provide the oil tank of our stove to which the burner is applied, with a specially constructed tube on a level with the float valve, whereby the torch is at all times in place and thoroughly saturated so that it is ready for use.

In operation the torch is inserted through the opening 28 within thehousing 21 and is likewise heated.

lighted. The air passes upwardly between the side walls 21 of the housing and through the perforated plates 26 to the burner and is heated and passes upwardly through the slot 22 directly against the lower face of thetube 12. This heats the tube 12, thus causing more rapid evaporation of the gasolene as is readily understood. The torch holds sufficient gasolene or other liquid fuel to thoroughly heat the tube 12 to start the burner. After the burner is started, it will be readily understood that the tube 12 is suficiently close to the burner to be heated, and the air passing in the open end thereof Vhile we have shown and described this specific form of auxiliary heater, it will be understood that this could be varied without departing from our invention.

Having thus described our invention, what we claim and desire to secure by Letters Patent is:

1. A heater for gasolene burners comprising an elongated housing having an open lower end and a contracted upper end, a tubular torch having a handle at one end and adapted to be inserted in the housing and means carried by the upper end of the housing for supporting the burner below the center of the air supply pipe of the evaporator of a burner.
